Medical, Biotechnology & Pharmaceutical


Ridout & Maybee LLP is a leading Canadian intellectual property law firm serving the biotechnology sector.

We represent top Canadian and international biotech clients, from start-ups to Fortune 100 companies, as well as universities, government agencies, and industrial associations.

Our professionals have degrees and decades of experience in biochemistry, chemistry, biology, chemical engineering, molecular biology and genetics, nanotechnology engineering, medical and health physics, cellular and molecular medicine, biomedical engineering, biomechanics, and plant agriculture. They have “boots on the ground” experience in “big pharma”, in pharmaceutical manufacturing, and at the Federal government biotechnology regulatory bodies. Our professionals are peer-reviewed, published authors in many of these fields.

We manage global patent portfolios for our clients and understand the nuances of obtaining and optimizing patent protection in subject matter fields with jurisdiction-specific rules – for example, methods of medical treatment, stem cell therapies, antibodies, diagnostic methods and instruments, and genetically modified life forms.

We have patent drafting and prosecution experience in a wide variety of subject matter, including:

  • Stem cell-based gene therapies
  • Gene transfer and expression methodologies
  • Adenovirus and other expression systems
  • Growth factors and growth factor analogs
  • Erythropoietin, analogs and isoforms
  • Apoptosis biomarkers, apoptotic entities and their therapeutic use
